In approving or disapproving any plat or certified survey map, the committee shall apply the standards set forth in this section. (1) Streets. (a) The arrangement, character, extent, width, grade and location of all streets shall conform to all official maps, may be required to conform to master plans, and shall be related to: existing and planned streets; topographic conditions; existing natural features including streams, lakes and tree growth; public convenience and safety; existing and proposed uses of land served by such streets; and the most advantageous development of adjoining uses. (b) The arrangement of streets in a subdivision shall provide, where possible, for the continuation or appropriate projection of existing or proposed collector and arterial streets in the area. (c) Local streets shall be laid out so as to discourage their use by through traffic. (d) Where a subdivision abuts or contains an existing or proposed arterial street, the committee may require marginal access streets, reverse frontage lots with screen planting contained in a non-access reservation along the rear of the property line, or such other treatment as may be necessary for adequate protection of residential properties and to afford separation of through and local traffic. (e) The number of intersections along arterial streets shall be held to a minimum. Wherever Page 75-7

8 75.19(1)(f) (1)(t) practicable the distance between such intersections shall be not less than 1200 feet. (f) Where a subdivision borders on or contains a railroad right-of-way or limited access highway right-of-way, the committee may require a street approximately parallel to and on each side of such right-of-way, at a distance suitable for the appropriate use of the intervening land. Such distances shall also be determined with regard to the requirements of approach grades and future grade separation. (g) Street jogs with centerline offsets of less than 150 feet shall be avoided. (h) A tangent at least 100 feet long shall be introduced between reverse curves on arterial and collector streets. (i) Streets shall be laid out so as to intersect as nearly as possible at right angles, no street shall intersect any other street at less than 75 degrees, and not more than two streets shall intersect at one point. (j) Reserve strips controlling access to streets shall be prohibited except where their control is definitely placed in the committee under conditions approved by said committee. (k) All street rights-of-way shall be of the width specified on applicable official plans and official maps or, if not specified therein, they shall not be less than the width specified in section 75.19(1)(o) below. (L) The minimum radius of curvature on the centerline shall be as specified in section 75.19(1)(o) below. (m) The maximum street grade shall be as specified in section 75.19(1)(o) below. (n) The design of the vertical alignment of the centerline shall be based on the minimum safe stopping sight distance in accordance with the design standards of the American Association of State Highway Officials. (o) Streets Principal Standard & Primary Arterials Arterials & Col- Marginal lectors Local Access Minimum Right of Way Minimum Right-Of- Way Width in Feet Minimum Radius of Curvature in Feet of Centerline Maximum Grade 6% 8% 10% (p) Cul-de-sacs shall not exceed 1000 feet in length and shall provide a turn-around with a minimum right-of-way radius of 60 feet. The traveled way within the cul-de-sac shall provide a minimum radius of 40 feet. (q) Dead-end streets shall not be permitted without suitable turn-around. Appropriate arrangements shall be made for those parts of temporary turn-arounds outside of street right-ofway to revert to the abutting property owners at such time as streets shall be extended. (r) In commercial and industrial zoning districts, alleys or other definite and assured provisions shall be made for off-street parking, loading and service access consistent with and adequate for the uses proposed. The width of alleys shall be not less than 21 feet. Alleys shall not be permitted in residential areas. (s) Half streets shall be prohibited except where necessary for continuity of the street plan in the area. (t) Street names: 1. The committee may disapprove the name of any street shown on a plat which has already been used elsewhere in the area or which, because of similarity to the name of another street, may cause confusion. 2. Where a street maintains the same general direction except for curvilinear changes for short distances, the same name shall continue for the entire length of the street. 3. A name which is assigned to a street which is not presently a through street, due to intervening land over which a street extension is planned, shall be continued for the separate portions of the planned through street. 4. The name of the projection of a street shall continue the same suffix as the street even if the projection terminates in a cul-de-sac. 5. Access roads and highways served by them shall have the same street names and designation. 6. Approval of street names on a preliminary plat will not reserve the street name nor shall it be mandatory for the committee to accept it at the time of final platting. Page 75-8

9 75.19(2) (6)(c) 7. All street names shall be consistent with chapter 76 of the Dane County Ordinances. (2) Utility easements. (a) Easements across lots or along rear or side lot lines shall be provided for utilities where necessary, shall be at least 6 feet wide on each side of lot lines, and shall be designated as "utility easement" on the plat or certified survey map. The committee shall solicit the recommendations of the utility companies regarding utility easement needs to service the subdivision. (b) In residential subdivisions, lots shall be served by underground electric, cable TV and telephone utility lines unless waived by the committee. Land disturbed by such installation shall be restored. (c) Where utility facilities are to be installed underground, the utility easements shall be graded to within six (6) inches of the final grade by the subdivider prior to the installation of such facilities, and earth fill, piles or mounds of dirt shall not be stored on such easements.

(e) Utility facilities when installed on utility easements, whether overhead or underground, shall not be closer than one (1) foot to a property line or three (3) feet to any monument. (f) Where a subdivision is served by an existing overhead facility, the facility may be utilized and improved with the approval of the committee. (3) Drainageway easements. Where a subdivision is traversed by a water course, drainageway, channel or stream, there shall be provided an adequate drainageway easement as required by the committee. The location, width, alignment and grading of such easements shall be of such a width and design to accommodate the anticipated discharge from the property being subdivided and also the anticipated runoff that will occur when property at a higher elevation in the drainage basis is developed. (4) Setbacks. Where the lots abut navigable waters, building setback lines for all buildings and structures, except piers, marinas, boathouses and similar uses, shall be shown on the plat and shall not be less than 75 feet from the normal high water line. (5) Blocks. (a) The length, width and shape of blocks shall be suited to the planned use of the land, the applicable zoning requirements, the needs for convenient access, control and safety of street traffic, and the limitations and opportunities of topography.
